I was wondering if anybody on here knows a way to buy call options in a major US company (Alphabet, which is Google's parent company) from the UK. IG Index, for example, offer options trading on the Dow Jones and futures trading on Alphabet, but that's not exactly what I want.

Thanks in advance to anyone who can give me a hand with losing a pile of cash on a speculative, uninformed bet that I've got no business going anywhere near.
